FTP Client and Server Subcommands Associated with Operation IdentifiersOperation Identifier Client Subcommands Server Subcommands0 - Initialize Session OPEN new connection11 - Create Directory/Library MKD, XMKD2 - Delete directory/library RMD, XRMD3 - Set current directory LCD CWD, CDUP, XCWD, XCUP4 - List directory/library LIST, NLIST5 - Delete files DELE6 - Send files APPEND, PUT, MPUT2 RETR7 - Receive files GET, MGET 2 APPE, STOR, STOU8 - Rename files RNFR, RNTO9 - Execute CL commands SYSCMD 3 RCMD, ADDM, ADDV, CRTL, CRTP,CRTS, DLTF, DLTL:Notes:1. The exit program is called with this operation identifier each time the FTP server receives a connection request.2. For the MGET and MPUT subcommands, the exit program is called once for each file that is sent or retrieved.3. If an exit program is associated with exit point QIBM_QTMF_CLIENT_REQ, the F21 (CL command line) key isdisabled and the user must use the System Command (SYSCMD) subcommand to run a CL command.The following notes apply to the REXEC server (application identifier 2):1. The only valid values for the operation identifier are 0 and 9.2. If the returned Allow operation output parameter is not valid, the REXECserver will not allow the operation and the message ″Data from exit programfor exit point &1 is missing or not valid″ is issued to the job log.88 OS/400 TCP/IP Configuration and Reference V5R1
